HANNA HI9125 Portable pH/ORP Meter

The HI 9125 is a waterproof pH meter that can utilize ORP (oxidation reduction potential) electrodes.

A large dual-level LCD displays both the pH and temperature along with an operational guide. Graphic symbols are displayed to help the users during the calibration process.

The pH calibration procedure is automatic with five memorized pH buffer values and buffer recognition to simplify the calibration process.

This meters utilizes the HI 1230B double junction pH electrode. The double junction helps to minimize junction contamination for accurate, consistent results.
